Official summary
Some 2021-2023 Bronco vehicles built on or before 31-May-2023 may exhibit a whistle noise below the lower left windshield area at the bottom of the A-pillar. This may be due to a missed body sealer application at the factory. To correct this condition, follow the Service Procedure to reseal the affected body seam.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
